生态港口评价指标体系的构建—基于R聚类、变异系数与专家经验的分析

The ecological port evaluation indicator system based on r-cluster,coefficient of variation and expert experience

从"生态文明"与"绿色经济"的角度,海选与生态港口相关的评价指标,在细化分析生态港口压力因素、承压因素和状态因素的基础上,构建了包含准则层、因素层和指标层的生态港口评价指标体系;遵循目的性、可行性和可观测性原则,利用R聚类-变异系数分析,定性与定量相结合地筛选了评价指标,并融入了专家的主观分析,完善了生态港口评价指标体系。结果表明,筛选出的21.30%的指标可反映93.91%的原始信息,证明了生态港口评价指标体系的合理性。

From the perspective of ecological civilization and green economy, this paper has extensively selected the evaluation indicators related to ecological port. Based on a refined analysis of the pressure - state - impacts factors on ecological port, the ecological port evaluation indicator system which contains a hierarchy structure with criteria, factors and indexes is established. Following the principles of purposiveness, feasibility and observability and using the methods of r - cluster and coefficient of variation, the ecological port evaluation indicators are screened with the combination of qualitative and quantitative analysis. Then, the ecological port evaluation indicator system is improved by the application of experts＇ subjective analysis. The results reveal that final ecological port evaluation indicator system has been proven that it can use 2l. 30% of initial indicators to reflect 93.91% of original information.
